IPC: G01N21/35
Filed: 1993-09-17
Abstract: PURPOSE:To manufacture an infrared type gas sensor which is easy to manufacture and has good responsiveness, good reproducibility and high analytical precision. CONSTITUTION:Two sample cells 11, 91 made of silicon are stuck together via an interface 51. Grooves constituting a sample gas passage 120 and a reference gas sealing space 130 are formed in the respective silicon sample cells 11,91. The silicon sample cells 11,91 are stuck together to form the sample gas passage 120 and the reference gas sealing space 130, and evacuation is carried out and gas is substituted so that an inert gas is sealed in the reference gas sealing space 130.

And, insulating films 20 and 24 are deposited on the substrate 10 containing the wirings 18 and 22 at the temperature lower than that copper is oxidized at. As the insulating films 20 and 24 are adhered onto the wiring 18 and 22 at the temperature lower than that copper is oxidized at, copper contained in the wirings 18 and 22 is prevented from oxidation during a high temperature treatment. By these processes, a copper wiring can be kept low in resistance value even after a high temperature treatment.

Abstract: PROBLEM TO BE SOLVED: To reduce the pop sounds which are generated when the volume amplification factor is varied by preparing a calibration means which controls the input offset of a volume of the preceding stage to secure the coincidence of input offsets between the said volume and a volume of the next stage. SOLUTION: A 1st switch part 23 is turned off with a switch 12 or 13 turned on, an operational amplifier 7 of a volume 1 is set at a voltage follower and the input offset voltage V01 is generated at an output terminal 3. Then a 2nd switch part 25 is turned on and the output voltage V01 (equal to the input offset voltage V01 of the amplifier 7), as the output offset of the terminal 3 is inputted to an inverted input terminal 19 of an operational amplifier 15. A calibration means 24 inputs the offset voltage that sets the offset difference at 0 between the volumes 1 and 4 to a non-inverted input terminal 22 of the amplifier 15 via an offset voltage generation means 26 under the control of a control circuit 27. Thus, the pop sounds can be reduced in a simple constitution.

Title: Electroluminescence lighting system
Inventor: ONO SHINICHIRO
IPC: H05B33/00
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To realize a device having a small circumferential nonluminescent part and a narrow edge by mounting a power supply band along one side of a transparent electrode, folding ends of the transparent electrode and a fluorescent layer from a front side to a back side, and mounting the power supply band at the back side so that it is extended along the extending direction of a folding line. SOLUTION: The light from a fluorescent layer 3 penetrates through a transparent electrode 2, and a surface at the transparent electrode 2 side totally generates the light. As the transparent electrode 2 has a comparatively high resistance, the loss of voltage increases and brightness decreases at the part farther separated from a center of contact point, when the transparent electrode 2 is connected to an input terminal 4 on a pin point similarly as a back electrode 1. To reduce the unevenness of the brightness, a power supply band 5 formed by coating the silver paste into the band shape, is placed along a side of the transparent electrode 2, and the input terminal 4 is connected to the power supply band 5. As the input terminal can be contacted with the transparent electrode 2 with a wider area by the power supply band 5, the evenness of brightness can be improved.  A part of the power supply band 5 is folded to a back surface (back electrode 1 side), and the whole is sealed by a package film 6 to from a sealing part 7.

Title: Protective device for impact head
Inventor: HORI FUSAO
IPC: H02H9/02
Filed: 1989-09-08
Abstract: PURPOSE:To positively protect an impact head from overcurrents by operating a control means when actual voltage is made higher than set voltage and preventing power supply to the impact head. CONSTITUTION:When a comparison output signal S1 (an inversion signal at the time of normalcy) at the time of the generation of overcurrents is transmitted over a power circuit 2 and a connection circuit 12, the power circuit 2 stops the supply of power, and the connecting circuit 12 brings a power supply line to the state of disconnection. Consequently, the supply of power can rapidly be interrupted when the overcurrents of an impact head 1 are generated. Accordingly, an accident such as the fuming, firing, etc., of the impact head due to overcurrents can be prevented, thus positively protecting the impact head 1 stably without a malfunction, then improving the reliability of the impact head.
